3. The hydrogen atoms have a partial positive
charge and the oxygen atom has a partial
negative charge.This unequal distribution of
charges make the water molecule polar.
4. The partial negative end of
the oxygen atom is
attracted to the partial
positive end of the
hydrogen atom on an
adjacent molecule.
The hydrogen bonds give
water its unique
properties.
5. Water exists naturally on Earth as a solid,
liquid, and gas.
6. Water is often described as a universal
solvent. It is capable of dissolving a variety
of different substances: polar or ionic
substances, but not nonpolar substances.
“Like dissolves Like” – polar dissolves
polar.
It is water's chemical composition and
physical characteristics that make it such
an excellent solvent.
7. Scientists were working in a lab day and night,
trying to identify a universal solvent. One
day, one of the scientists yells out,“I found the
universal solvent! It dissolves everything it
comes into contact with!!” All the other
scientists gathered around to admire a beaker
full of a clear, colorless, odorless liquid. All
were excited as they cheered. What do you
think, did he discover it?
